The testers at Edwards AFB, Calif., have begun integration testing for the use of the Small Diameter Bomb with the F-22 Raptor. The new stealth fighter can accommodate four SDBs and its BRU-61 carriage in each weapon bay for a total of eight small bombs and two Advanced Medium Range Air-to-Air Missiles. Boeing flight test engineer Jeff Randolph, heading the SDB program at Edwards, says the 250-pound SDB is more practical for use in urban environments than older larger bombs.
The KC-Z4, a blended wing body tanker concept being developed by startup JetZero, could fuel larger groups of aircraft at longer range to hold more targets at risk, company officials say.
